BOOTH, OF DETROIT, MICHIGAN, ASSIGNOR T KE LSEY-HAYES WHEEL CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF NEW YORK RIM SIZING.AND PUNCHING MACHINE Application filed July 1, 1925, Serial No. 40,943.

The invention relates to machines for sizing and punching rims and is designed particularly for use in'sizing and punching vehicle wheel rims such as demo'untable rims and permanent rims or fellies. One of the objects of the invention is to provide a continually operating machine, which is arranged to successively size and punch the rim during one cycle at the end of which the sized and punched rim may be removed and replaced by another rim to be sized and punched. Other objects are to provide a simple arrangement for guiding both the rim sizing blocks and the rim punch; to

'provide heads which are reciprocable in directions transverse to those of the rim sizing blocks and punch for actuating the same; and to provide revoluble means for reciprocating the heads and thereby actuating the rim sizing blocks and punch. A further object is the provision of means for shrinking a transversely split rim and then shearing its end portions to make the same parallel. With these as well as other objects in view the lnvention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth;

In the drawings Figure 1 is an end View, partly broken away, of a rim sizing and punching machine embodying my invention;

Figure 2 is a vertical memkan section therethrough v Figure '3 is a cross section on the line 3 -3 of Figure 2; v

4 Figures 4, 5 and 6 are cross sections, respectlvely, on the lines 4-4, 5-5 and 66 of Figure Figure 7 is an enlarged plan view of the structure shown in Figure 5.'

As shown in the present instance, the machine is employed to size and punch a demountable rim 1, which is of the transversely split type and is provided with the apertures 2 near its endsv for the passage of the rivetsfor securin tures 3 for the passage of the valve stem the interlocking plates tothe ends of the rim, with the ap'er-' passage of the rivets for securing the rim dr ving lug. The machine has the annular series of radially inwardly movable blocks 5 which are engageable with the rim to shrink the same to size and also the radially outwardly movable holders punches and the supporting blocks 7 which are diametrically opposite the holders for the punches which form the apertures 2 and 3,.in the rim. 1

Each block 5 is mounted upon the radially movable segmental shaped slide 8 and each punch holder 6 and supporting block 7 slidably engages in vthe radially extendin channel 9 of the slide 8 at the side thereo The slides 8 slidably engage in radially extending channels 10 formed in thehead- 11 of the machine Any suitablev means may be employed for holding the slides 8, blocks 7 and holders 6 in assembled position, herein shown as comprisin a pair of rings 7' and 8 secured to the l iead 11 by means of the bolts 11.

For actuating the blocks 5 the head 11 is reciprocated in directions transverse to the radial movements of the blocks. As shown, the machine has the annular stationary abutment or frame member 12, which surrounds the slides 8. Intermediate these slides and the stationary abutment or frame member are the toggle links 13, which preferably have their ends journaled upon the pins 14 and 15, respectively, secured to the slides 8 and stationary abutment or frame member 12. The head 11 is secured to the hollow shaft 16, which extends rearwardly .shaft.-, The cams 18 are secured upon -the crankshaft 2O whichis journaled in the base 21 of the machine and is suitably driven by reduction gearing. For holding the rollers 6 for the 19 against the cams 18 I have provided suitable resilient means such as the coil springs 22 which extend from the head 11 to the lower rear end of the frame member 17.

For actuating the punch holders 6 and sizing blocks supporting blocks 7 there is the head 23 which is mounted upon the shaft 24 and is adapted to be reciprocated by means of the shoulder 25 upon the shaft and the nut 26 threaded upon the end of the-shaft, the arrangement being such that the head 23 has a lost motion connection with the shaft 24: and that the amount of travel of the head may be varied. Rotation of the head 23 relativie to the shaft 24 is prevented by means of a longitudinally extending key at shaft 20 through the link 30 whichpivotally connects the crank shaft to the shaft and is located between the cams 18.

With the arrangement as thus far set forth, it will be seen that my machine may be continuously operated to move the rim and punches, and supporting blocks in timed relation to each other to successively size the rim and punch the same. It will also be seen that a sufficient time interval may be allowed at the end of each cycle to remove the sized punched rim and replace the same with another to be sized and punched.

For the purpose of sizing the transversely split rim and providing ends which are parallel to each other, the punch holder 6 for holding the members 31 which ierce the apertures 2 also holds thecombined positioning and shearing member 32 which is located between the piercing members 31. This combined positioning and shearing member has the outer reduced pilot portion 33 which is normally located between the ends of the rim beforeits end portions are sheared. This member also has the radially inwardly positioned enlarged portion 34 providing the parallel shearing shoulders 35 which are. brou ht into engagement with the end portions of the .rim, after the latter has been shrunk to size, to shear these end portions and thereby make theends of the completed rini parallel to each other, allowance having been made for the stock removed from the rim so that the final dimensions of the rim are correct. The piercing members 31 are located relative to the shearing shoulders 35 so that they come into engage- I ment at practically the same time as the shearing shoulders. The block 5 radially 'uating said blocks and outward from the punch holder 6 for the combined positioning and'shearing member and piercing member also functions to hold the die 36 for cooperating with these memhere The blocks 5 radially outward from the holders for the members 37 and 38 which pierce the apertures 3 and 4, respectively, in the rim, also hold suitable dies 39 and 40 respectively, for cooperating with their respective piercing members.

The supporting blocks 7 are so arranged that they comeinto contact face of the rim diametrically opposite the combined positionin and shearing member 32 and piercing mem ers 31 and the piercing with the inner member 37 at the time these members are operating upon the rim, thereby holding the rim to size.

The parts are so arranged that the blocks 5 are first moved radially inward to shrink 1. In a rim sizing and punching machine,
